Consider a power system consisting of N number of buses. Buses in this power system are categorized into slack bus, PV buses and PQ buses for load flow study. The number of PQ buses is NL. The balanced Newton-Raphson method is used to carry out load flow study in polar form. H, S, M, and R are sub-matrices of the Jacobian matrix J as shown below:

The dimension of the sub-matrix M is
  • a)
    (N - 1) × (N - 1 NL)
  • b)
    NL × (N - 1 + NL)
  • c)
    (N - 1) × (N - 1 + NL)
  • d)
    NL × (N - 1)
Correct answer is option 'D'. Can you explain this answer?

Newton Raphson method for load flow study in polar form

The submatrix M relates between [ΔQ] and [Δδ]
Number of elements in ΔQ vector = Number of known Q 
Number of elements in ΔQ vector = Number of PQ buses = NL
Number of elements in Δδ vector = Number of unknown δ = N - 1
Size of matrix M = NL × (N - 1)
Size of other sub-matrix:
H = (N - 1) × (N - 1)
S = (N - 1) ×  NL
R = NL × NL
